Question

Solve for x in the equation x^2 - 10x + 25 = 35.

Answer 1

Explanation:

According to the equation, we have to solve for x :

x² - 10x + 25 = 35

x² - 10x + 25 - 35 = 0

x² - 10x - 10 = 0

Using Quadric Formula,

x = - b ±√b²-4ac / 2a

x = - (-10) ±√(-10)² - 4(1)(-10) / 2(1)

x = 10 ±√ 100 + 40 / 2

x = 10 ±√ 140 / 2

Taking common "2"

x = 2 (5±√70) / 2

Both "2" will cut with each other

So,

Now we have

x = 5 ± √70

This is the required "X" In the equation
